Title: Turbine controller
Inventor: HOSHI HIROYUKI
IPC: F01D17/20
Filed: 1990-11-15
Abstract: PURPOSE:To prevent any increase in turbine inlet steam pressure or nuclear reactor dome pressure for stable control by providing a signal switching portion for outputting a turbine bypass valve forcibly opening degree set value and an adder for adding the turbine bypass valve forcibly opening degree set value to a turbine bypass valve opening command value. CONSTITUTION:A signal switching portion 25 is constituted of a turbine bypass valve forcibly opening degree setter 26 and a relay contact 27. The relay contact 27 is closed on the basis of a CV closure failure signal upsilon19. Upon closure of the relax contact 27, a turbine bypass valve forcibly opening degree set value is added to a TBV opening deviation upsilon11 which is obtained by subtraction of a CV opening command value upsilon8 from a pressure control command value upsilon7 by an adder 28a, thus obtaining a final TBV opening command value upsilon13. In the case where a CV closure failure occurs during a pressure control operation, the CV closure failure detector 24 detects a CV closure failure, to forcibly open a TBV 6. Therefore, it is possible to prevent any increase in turbine inlet steam pressure or nuclear reactor dome pressure. Furthermore, a CV 6 stably controls the turbine inlet pressure or nuclear reactor dome pressure.

Title: Method for packaging ic chip
Inventor: FUJITA MASANORI
IPC: H01L21/60
Filed: 1986-12-24
Abstract: PURPOSE:To easily package an IC chip on an electrode substrate by a method wherein the IC chip where a conductive elastomer layer, which is formed to be higher than the surface of the IC chip, is attached to a bonding pad of the IC chip is arranged face to face with the electrode substrate and this assembly is pressed and held. CONSTITUTION:An IC chip 1 is aligned with an electrode substrate 6, which has an extraction electrode 5 facing a bonding pad 2, and is fixed by a pressing metal fitting of a springy pressurizing support means 7. By this packaging method, the bonding pad 2 of the IC chip 1 and the extraction electrode 5 of the electrode substrate 6 become electrically conductive; the IC chip can be used perfectly for consumer appliances without the bonding. If an adhesive elastomer layer is used as the conductive elastomer layer, the IC chip and the electrode substrate are fixed temporarily, their positions are not shifted while they are being clipped by the pressing metal fitting; they are held easily. Because the conductive elastomer layer is attached to the IC chip collectively. The alignment with the electrode substrate becomes easy; it is enough to align the layer with the electrode substrate and to press and hold the assembly; accordingly, it is possible to package all the terminals easily by one process even when the number of terminals is increased.
